Here I have some C++ code to remind, more me than anyone else, how some of the sintax are.

bucket_sort1 bucket_sort2	calculator	struct
digits	face	function_template
heap_sort	is_digit	limit
merge_sort	new_array	pointers
quick_sort	random	return_struct
setprecision	shell_sort	showpoint
struct	struct_as_parameter	structArrayOfPointers_param
Create Directory / File	sizeof array of integers	size of a file (iostream)
CreateProcesw (WIN32 API)	size of a file (WIN32 API)	copy a file (WIN32 API)
postfix calculator	try-catch	thread_matrix_mul(WIN32_API)
stringstream
